If, like many people, you use iTunes as your primary media management system to organize and play your audio and video files, you may reach a point when your content begins to fill up your hard drive and you get dangerously close to running out of space.

Although the vast and thronged expo floors of CES 2015 are brimming with a breathtaking array of electronic devices and gadgets, the majority have one thing in common: the ability to communicate with smartphones.

Integration with smartphones is something we consumers have come to expect and even demand from our electronic products. Nearly every pitch you hear at CES, whether it’s for a fitness tracking device, a camera, or a washer and dryer, follows the script of, “This product can do x, y, and z—and of course you can control it from your iOS or Android device.”

And if there’s one thing made obvious by spending a week at CES, it’s that there are a lot of things you can do when you pair your phone with the right device.
